ADJUSTABLE SCREEN AND SASH FOR WINDOWS.

SPECIFICATION forming part of Letters Patent No. 767,896, dated August I6, 1904.

Application filed July 24, 1902.

To all whom it may concern.-

Be it known that I, HERMAN HENRY KERCK- HOFF, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Adjustable Screens and Sashes for WVindows, of which the following is a specification. v

This invention is applicable to the sashes IO and frames of window-screens and other closures for window-openings.

An object of this invention is to provide a cheap, simple, readily-applied, and neat device for adjusting the tongues of sashes or 5 screen-frames.

The accompanying drawings illustrate the invention.

Figure I is a broken view showing a window-screen in place in a window provided with this improvement. Fig. II is a fragmental enlarged detail illustrating the improvement in one form. Fig. III is a view of another form of the invention. Fig. IVis a detail view showing parts of the device sep- 5 arated. v

1 designates a window-frame of the usual construction, 2 a grooved member of a sash or screen-frame of the ordinary construction, and 3 a movable tongue moving in a groove 3 4. in one side of the screen-frame.

5 is a longitudinally-movable member, de'

sirably a screw, having a cylindrical head a, a swivel-polnt Z2, and an intermediate screwthreaded portlon c.

6 is an attaching-piece desirably formed of a bent-metal plate, having a portion d swiv' eled to the end of the screw and oblique portions 6 and f, which are seated in transverse oblique grooves or slots g and/i, desirably 49 formed by transverse saw-kerfs in the movable tongue 3, which slant toward the ends of the tongue and desirably diverge toward the axis of the tongue, so that when the parts are assembled the attaching -piece will be locked within the cut-away portion of the Serial No. 116,844. (No model.)

tongue. A portion of the tongue is desirably removed from between the grooves to leave a'recess for seating the middle portion of the plate, so that said plate will be flush with or wholly within the tongue. The diameter of 5 the cylindrical head of the screw may be either greater or less than or the same as that of the screw-threaded portion thereof and is shown in two ways in the drawings. When the screw is of the same diameter throughout, as shown in Fig. II, it may be screwed point first through a hole c'in the frame member toward the groove in saidv frame. When it is of less diameter, it may be inserted through the groove and screwed head first through the member 1 of the frame from the groove. In the first-mentioned form the screw may first be screwed through thestile member 2 of the frame and the attaching-piece then applied to the point and riv- 5 eted thereon, after which such piece will be forced into the grooves in the tongue. In case the head is the smaller, as shown in Fig. III, the attaching piece may be riveted to the screw before screwing it head first through the stile, 7 thereby avoiding danger of bruising the sash when the attaching-piece is riveted to the screw, thus effecting an improvement which,

so far as I am aware, has hitherto been unknown in the art to which my invention pertains. In any case the attaching-piece may be manually secured to the tongue by sliding it laterally into the saw-kerfs.

In practical use there will ordinarily be for each adjustable tongue two adjusting-screws, each arranged as hereinbefore set forth, and each will desirably have the usual slot 1' for turning the same. The hole through the'sash member will desirably be of the same diameter as the cylindrical head of the screw, so 5 as to give a neat finish. WVhen the head portion is of smaller diameter than the screwthreaded portion and the screw is inserted through the groove and screwed outward, there will be no marring of the exposed face 9 of the frame member 2, and when the screw is in place the cylindrical head Wlll fit closely in the hole and a neat appearance will be presented.

The groove L is desirably deep enough to fully seat the tongue 3, so thatby turning the screws the tongue may be fully drawn into the grooved member 2 in order to insert the same into the window-frame, whereupon the screws may be turned in the usual way to move the tongue out of the groove 4 and into the groove in the window-frame to produce the required tightness of joint and desirable friction between the sash and the frame in which it moves;

It is to be understood that this invention is not limited to the use of a screw to move the tongue, but that any suitable longitudinallymovable member may be swiveled or otherwise attached to the plate to. impart an edgewise movement to the tongue. The part which performs the function of the bent plate shown in the drawings need not be seated in a cutaway portion having the form of grooves; but

said cut-away portion of the tongue may be of any suitable form which increases in longitudinal extent as it increases in depth. Such cut-away portion or slot in the tongue will, however, in any case extend to one or both sides of the tongue, so as to be open on the side for the insertion of the attaching bent plate, and the bent plate and the slot for the same will extend inwardly from the edge of the tongue and also longitudinally of the tongue, so that when said bent plate is inserted in said slot from the side it will be in such engagement with the tongue that direct inward and outward movement of said plate edgewise of the tongue by adjustment of the screw member 5 will cause a similar movement of the tongue. The slot being opened at the side, I depend on the engagement of the sides of the groove in the sash with the edges of the bent plate to hold the latter from turning in the tongue or from sidewise displacement. Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is v 1. The combination of a grooved member having a hole therethrough, a longitudinallyadjustable member extending through the hole, a tongue fitting movably in said groove and having a cut-away portion extending inwardly from its inner edge and also longitudinally of the tongue, said cut-away portion being open at the side of the tongue, and an attaching means connected to the aforesaid adjustable member and extending inwardly and longitudinally of the tongue to engage therewith in directions longitudinal and edgewise to said tongue, and said attaching means engaging sidewise with the groove to retain said means from rotation and from sidewise displacement.

2. The combination of a groove member having a hole therethrough, an adjustingscrew member extending through the hole, a tongue fitting movably in the groove and having a cut-away portion extending inwardly and longitudinally from a side edge of said tongue, said cut-away portion being open sidewise of the tongue, and an attaching means extending inwardly and longitudinally of the tongue to engage therewith in directions longitudinal, and edgewise of the tongue but free of sidewise engagement with the tongue so as to be adapted to he slid into said cut-away portion, and said attaching means engaging sidewise with the groove to retain said means from sidewise displacement.

3. The combination of a grooved member having a hole therethrough; a tongue moving in the groove and having slots extending crosswise of the tongue and obliquely toward the ends of the tongue; a screw in said hole; and an attaching-plate having a portion swiveled on the screw, and oblique portions in said slots, said plate being manually attachable to the tongue.

4. The combination of a grooved member having a hole therethrough; a tongue moving in said groove and having transverse slots which slant toward the ends of the tongue; a screw screwed in the hole and an attaching member swiveled to the screw and having oblique portions adapted to slide laterally into said slots but locked therein by the walls of the grooves when the parts are assembled.

5. The combination of a tongue having diverging slots extending thereinto from an edge thereof; with an attaching-plate having end portions adapted to slide laterally into said slots; grooved members locking said'plate in operative position; and a screw swiveled to the central portion of said plate to impart an edgewise movement to the tongue.

6. In a window sash, in combination, a tongue having a cut-away portion extending inwardly from a side edge thereof, said cutaway portion increasing in longitudinal extent as it increases in depth, a piece adapted to slide into said cut-away portion of the tongue from the side thereof but being locked therein when the parts are assembled, a screw having a head of less diameter than the threaded portion thereof, and a grooved member having a hole leading from the base of the groove, said hole being adapted to receive the screw and engage the threaded portion thereof.

7. In a window-sash, in combination, a tongue provided with saw-kerfs which extend divergingly inward from a side edge thereof,

to this specification, in the presence of two subscribing witnesses, at Los Angeles, in the I county of Los Angeles and State of California, this 18th day of July, 1902.
